Research On The Computer Intrusion Detection Technology On The Basis Of Immune Principle

On the basis of past research result ,this paper has done further theory discuss and research of the computer intrusion detection technology on the basis of immune principle and point out the shortage of the original negative selection algorithm by the analysis and contrast (1) It is not highly efficient that the original algorithm produces valid detectors by randomly generating strings and then matching them with self strings. (2) The detectors generated by the original negative selection algorithm may match each other, so the information expressed by the detectors is redundant and their detecting coverage becomes small . To solve this problem, an improvement algorithm is put forward. It is also proved that the improvement is advanced and correct by theory analysis and experiment in contrast.
